A questionnaire was sent to 700 optical and optometrical practices in Hong Kong in February 1992 to survey the state of contact lens practice in Hong Kong for the year 1991. There were 174 replies. During the year surveyed, each respondent fitted an average of 540 patients with contact lenses, 44 per cent of which were refits. Of all the contact lenses fitted, 86.9 per cent were soft contact lenses, 8.8 per cent were rigid gas permeable lenses and 4.4 per cent were PMMA lenses. Eighty per cent of the practices dispensed extended or flexible wear contact lenses and, on average, the maximum period of continuous wear recommended was 4.8 days. The most popular soft lens disinfecting regime recommended was the hydrogen peroxide system, and most respondents recommended mechanical rubbing of lenses during daily cleaning, irrespective of the disinfecting regime used. Compared to the previous survey, the results showed a continued low usage of speciality lens types, although there was increased usage of toric lenses.
